Abstract
Frames for batteries which are constructed of planar battery cells prevent the planar battery cells from shifting while the batteries are vacuum sealed. These frames do not add to the thickness of the batteries but have the advantage of increasing the rigidity of the battery, reducing the shifting of the battery cells during assembly, and preventing vulnerable edges which result in non-uniformities and low energy density. The interlocking frame design allows cells to be stacked onto a battery with relatively tight alignment, high volumetric efficiency and improved safety.
